EFV1-10-C - Proportional Valve
Proportional flow, normally closed, poppet
Up to 38 L/min (10 USgpm) • 210 bar (3000 psi)
Description
This is a 2 way 2 position,
pilot operated spool type,
normally closed, proportional
flow control screw in cartridge
valve. Ideal for speed control
and in conjunction with
pressure compensators to
provide proportional pressure
compensated flow control to
any actuator.
Operation
The valve is controlled by
current supplied to the coil.
At zero current, the valve is
fully closed from port 3 to
port 2. At 1500 mA (12V coil)
the valve is considered fully
open. This is the maximum
intended current level for use
in applications. Port 1 is used
for pressure balancing the
spool and armature and must
be blocked in all cases. The
maximum intended pressure
drop is 300 PSID. At pressure
drops above 300 PSID,
almost no increase in flow is
obtained. The intended flow
direction is from port 3 to port 2.
Operation of the valve with
flow from port 2 to port 3 will
produce flow vs current and
flow vs pressure drop curves
that are significantly different
from those obtained with
flow from port 3 to port 2.
Since the spool and armature
are pressure balanced, the
operating pressure does
not affect the operating
characteristics of the valve.
The operating point of the
valve is determined only by
current, pressure drop and
temperature.
Features
Hardened and ground working
parts to give long life with good
control; Compact design with
low pressure drop.IP69K Tough
coil compatibility, continuously
rated.

Note: To determine operating characteristics
for the flow rating selected, at a specific
differential pressure, first determine
maximum flow from upper curve at the
differential pressure value. This will be
the “100%” flow on the lower curve.
